The folder deployment conondrum-Vulnerability while drawing.

Hey Guys,

I have noticed a peculiar issue while deploying my folder.It is a great weakness which can be exploited rather easily.I am posting pictures so that you may try it with a folder of your own.I use a particular method, to be applied when a fast draw is needed.I don't know what order the pics will be in, so i'll number them.

The pics are clicked with the folder in my left hand.They are for reference, but the position of my fingers change when the folder is in my right hand.The problem is present in either hand.

OK.This is what i do.Index finger used to flick open blade.Thumb on pocket clip ( right hand ) and tips of index and ring finger used to support on opposite side.Pinkie not used.

Flick open blade by pressing stud with index.Blade opens partially.

Use movement of hand to provide momentum for the blade to click into place.

Open hand for a moment and grip the handle securely.Up unto this point, the blade can easily be knocked out of my hands.Is there a better way? It takes me about half a second to go from having it just out of my pocket to being ready to use it.

Picture below shows thumb and index positions.

1 shows other finger positions.2 shows first step done-Blade out partially.3 shows finger positions while blade is out partially.4 shows blade fully out using outward movement of hand, and switched to secure grip.Note- Fingers remain as shown in 3 till i open my hand and change grip.

Skyman,

This is an attempt to explain, though the best results will come through your experimentation and practice. You may find a much better way :

The 'flipper' should help deploy the blade completely. Without wrist movement. It needs yout index finger to be at a higher angle than 90 degrees

Even if you use the wrist movement, the blade is deploying towards the back of your hand...hence you can grip the handle tighter, enclosed within your thumb and forefinger. The middle finger, ring finger and pinky will follow than enclose the handle once blade is fully deployed.

The better option (in case the flipper is not deploying the blade fully) is to use the thumb studs. Hold the handle firmly, the thumb should be at a slightly higher angle, below, the thumb stud. Now flick the thumb up...like a coiled spring. The blade will snap out like a rocket and lock. No wrist movement needed. You might chip your nail a few times till this becomes second nature. Since your fingers are all close to the handle this is a much more stable option.

Third option...if the blade is thick enough...you can just flick it completely open with only wrist action. I saw your knife...and i think that you may be able to get past the detente on your knife. Hold firmly, shake down...release the blade...now flick open with wrist. However, in light of your last post on the smooth handle...please exercise extreme caution...this method is very risky.

Fourth option....take some stiff, yet malleable material like copper wise and wrap around the thumbstuds in a figure of 8. Leave a knob of this material on the top of the blade. When deploying, pull the blade around the seam pf your pocket. The blob of metal, will catch on the seam and the blade will be deployed and open, as you draw the knife handle out of your pocket. A very crude Emerson Wave technique. In Spyderco and other knives, you can use the deployment hole to attach some cable. Again, please be very very careful with this. One slip...and you could hurt yourself.

Fifth option. Take the knife out with your right hand. Rapidly deploy the blade with your left hand. This may sound silly...but done right, this is a very safe and very very fast way of deploying. Time yourself. And it may only take a fraction of a second longer...and is infinitely safer. With practice, it may even be faster.

Sixth option. Get a fast draw knife holster. They exist. Or make one yourself. Its not a complex design.

Hope this helps!

Looking for one-handed deployment, and the thumb stud idea i tried.Too tight.I guess the problem is- If the blade has to deploy, my fingers can't be in the way.That means i can hold the blade with my fingertips only while deploying ( If i am using one hand ) and so the flick is out of question.Maybe some other method in addition to the above eludes us?

look at the emerson wave and the cold steel spartan. they can be drawn from the pocket ready for use. no need of fancy thumb work.
the cold steel has chewed through a trouser of mine though !

Having considered the suggestions, i sat up with my blade last night.I found if i flick the very edge of the flipper hard with my index finger nail, the blade opens all the way to locked position.Which means while the blade is opening(past half way), i can wrap my fingers over the grips.Problem solved.No hand movement needed.

Tie a lanyard which you can loop around your wrist. Since you are new to the knife it's better this way, than the blade flying off from your hand and hurting yourself or some near and dear ones.

Will take your advice.OH, and i'm thinking of taking off the pocket clip to have a better grip.It gets in the way.

Have you considered loosening the pivot screw a bit? I typically loosen it to a point where there is no play in either direction, and the blade flicks open smoothly. Also ensure you loctite the pivot screw so it does not get loose as time passes, introducing blade play.

And as slingshot mentioned, with lot of practice and experience, you should be able to deploy the blade in any way you want.

AH.....what are fingertip pushups for? As of now the pivot screw is just tight enough to have absolutely no blade play.Once i source the loctite, will fine tune it to the ideal state and then apply loctite.And what was the name of the local loctite again? :oops: :oops:

Dude, you need to grow up -- just because you have an internet connection and helpful folks on this forum, does not mean you start squeezing everyone dry. I have responded to about 8 PMs' with information (including the question you ask above), and you show no respect for my time at all. Any further information you want from me will cost you money, pre-paid. Good luck with your knife hobby.

Amar, I've been reading about people using loctite on the pivot screws. Is this a glue going by the name. will it not clog the threads. What exactly is this and what is the correct way to do it.

Thanks

Loctite is a thread locking formulation. It is used on nuts, bolts and threads in machinery, tools etc where there are chances of the bolts unscrewing due to vibrations etc.

Check out http://www.loctite.in/Loctite-India.htm

Application: simple, clean the nut and bolt of any grease and apply a couple of drops of loctite on the threads and tighten. It will dry in a couple of hours.

It may be unscrewed again but will need some force and a tool to do. Yes, it will clog the threads but may be cleaned with a solvent and scotch brite or simply tighten it again with a few drops of loctite :wink:

I prefer the medium strength blue liquid.
